// *** before: ***
// one literal could hold at most 255 characters - an inheritance from
// the short string of Turbo Pascal. A longer text was cut into pieces
// and added up
const
  Help =
    'The first two hundred and fifty five characters of the help text ' +
    'ended right about here, so the rest had to start as a new literal ' +
    'and be joined with a plus sign, forever.';

// *** in version 12: ***
const
  Help =
    'A literal is no longer limited to 255 characters, so a long line of ' +
    'text can stay in one piece.';

// the compiler puts no limit on the length of a literal any more; what
// is left is the practical limit of the editor line, and a multiline
// literal is the tidy way to write a long text anyway
